GREENHOUSE AIR CONDITIONING

The main purpose of growing in a greenhouse is to protect the plant from unwanted external factors while trying to eliminate the dependence on environmental conditions. At this point, the climate factor, which is the biggest factor, comes into play. Greenhouse air conditioning elements can be divided into greenhouse heating systems, greenhouse cooling systems and greenhouse humidification systems.

GREENHOUSE HEATING SYSTEMS

Every plant has a temperature value that it needs to grow and bear fruit, and providing this value optimally is extremely important for the efficiency of production, but greenhouses have the feature of easy heating and cooling, so there are some features sought for heating;

  • The temperature in greenhouses should be adjusted independently of the outside temperature.
  • The set temperature must be evenly distributed throughout the greenhouse.
  • It must work efficiently and fuel must be easily and inexpensively supplied.

For this reason, we talked about the importance of planning in detail in our previous article titled greenhouse project preparation and greenhouse construction. For efficient and least costly heating, greenhouse cover material and greenhouse roof shape, greenhouse length and greenhouse height should be chosen in the most appropriate way according to current climatic conditions.

Greenhouse heating methods

  • Heating with stoves is a common heating method used by placing stoves using solid, liquid or gaseous fuels in the greenhouse at certain intervals and burning them.
  • Electrical heating is also done by firstly ensuring that the air flow applied on the electrically heated resistance is dispersed into the greenhouse, and the second method is provided by circulating the electrically heated water in the greenhouse.
  • Heating method obtained by circulating the heated water in a closed system in the greenhouse in heating with a central heating system.
  • Heating with hot air is also done by spraying the heated air into the greenhouse with pressure from the holes on the pipe through a pipe at regular intervals.
  • While solar energy is utilized in the heating method using natural energy sources, either the method of using the sun’s rays at the maximum level by positioning the roof slope according to the sun or heating with solar light collectors. In another method, geothermal energy is used. In this method, greenhouses are heated by using hot water and steam extracted from underground.

GREENHOUSE COOLING SYSTEMS

We have said that there is an optimum temperature value range that every plant needs in order to grow and bear fruit, if this value exceeds the optimum and reaches the maximum, then the environment for the plant must be cooled.

Cooling in greenhouses can be done with several different methods and systems. We can divide them as cooling with greenhouse ventilation, cooling with greenhouse fans, cooling with shading, and cooling with cellulosic pads.

Apart from ventilation and cooling, there may also be the aim of maintaining a healthy air and gas balance in the greenhouse.

The greenhouse ventilation system is the window systems that open to the outside of the greenhouse, generally located on the roof or close to the roof, and can be controlled mechanically or electronically. There are some technical features that these systems should have, these features are as follows. The greenhouse ventilation openings should be large enough, robust and leakproof when closed, and designed to create proper air circulation while this system is being installed.

In cooling with a greenhouse fan, it depends on the principle of removing the unwanted hot air in the greenhouse by providing the air inside the greenhouse with the outside air exchange with the help of the fans that open out from the greenhouse when desired.

Cooling with shading is the curtain systems that are installed in the greenhouse and can be opened and closed by mechanical or electronic methods when desired, and that provide shading on the plants by being installed parallel to the greenhouse ground.

Cooling with cellulose pads, on the other hand, are the systems that provide cooling in the greenhouse thanks to the cellulosic papers mounted vertically on the greenhouse wall, the water circulated inside and the humidity created by the exhaust fans.

GREENHOUSE HUMIDIFICATION SYSTEMS

It is very important to maintain the optimum humidity for each plant, because it protects the plant from freezing events in winter as a result of a sudden drop in humidity and a decrease in yield due to excessive heat in summer, while maintaining the heat balance in the environment, besides, excessive humidity can cause diseases to spread faster in the greenhouse. is extremely important.

Greenhouse humidification systems are provided by pulverizing water into the air by means of humidifier nozzles. While the water pulvirized into the air provides humidity, this humidity is distributed homogeneously into the greenhouse by means of the circulation fan placed at certain intervals in the greenhouse, and these systems can be operated at certain time intervals or with remote control, depending on the greenhouse automation systems, if desired.

As a result, greenhouse air conditioning, which is one of the most basic purposes of its installation, is extremely important for plant yield and producer. With the right air conditioning and greenhouse automation systems, high efficiency can be obtained from production while maintaining plant health.
